Most fitness apps pick one thing — a fasting timer, or a workout planner, or a calculator. This is the whole kit: run tracking, fasting, an ACFT-aligned plan, goal forecasting, and a score calculator for every branch's test.
Apple Health sync pulls every run with its GPS route map. Set your goal mile pace and watch your splits trend toward it — real miles only.
Intermittent fasting timer — 16:8, 18:6, OMAD, 24h, 48h — with a fast-log calendar, plus a weekly workout plan keyed to the ACFT events.
TDEE-based projection of when you hit your goal weight. Weight trend, fasting streak, recent workouts, and health check-ins, all in one feed.

Every screen below is built and ready for the mid-June launch. No concept art.
Body Builder reads your runs straight from Apple Health and lays each one out with its GPS route map. Set a goal mile pace and watch your splits trend toward it — no manual entry, real miles only.
Goal pace defaults to an 8:00/mi target (a 21:00 two-mile) and scales to whatever you set.
Body Builder reads your TDEE, your fasting protocol, and your average daily intake — and projects the exact date you hit your goal weight. Confidence improves as you log weigh-ins.
TDEE-based projection. Reads your protocol and intake against your maintenance calories, projects loss rate, names the date.
Weight trend. Apple Health-aware. Logs each weigh-in, smooths your trend line, tightens the projection confidence over time.
Fasting streak. Total fasts, this-week count, completed workouts — three numbers that decide your week.
Health check-ins. Automated prompts at 14h, 18h, post-workout — quick taps that build the record.
